ada_tensor_core_fp16
Ada Tensor Core FP16 GEMM prototype with WMMA-backed 32x64x16 correctness and timing harness.
This repository contains the standalone CUDA source for the ada_tensor_core_fp16 lane from
the PyC kernel lab. It is a source artifact for inspection and benchmarking;
it is not a precompiled binary and the result below is not a universal ranking.
Performance
| Kernel | GPU / architecture | Shape | Best recorded result | Evidence |
|---|---|---|---|---|
ada_tensor_core_fp16 |
not recorded | 1024x1024x1024 | 0.134 ms | Measured on not recorded, shape 1024x1024x1024; evidence hopper-tensorcore-bringup-20260421T191817Z.json. |
The result is reported with the original campaign's timing and correctness context. Compare kernels only when GPU, CUDA version, matrix shape, warmup, repeats, and reference/correctness mode match.
